Actions: Delete Selection deletes the selected action set

Delete Selection in the Actions panel (the bottom bar's trash and the
panel menu's new Delete) now deletes the selected action set with its
actions and keeps the other sets, after asking. A selected action is
still deleted at once. Shift-click on a set's name selects the sets from
the current one to it, and one question deletes them together. Default
Actions and the last set can be deleted; New Set still works on the
empty panel.

ui.actionSet.delete {sets?: [index]} does the deletion: an index past
the last set is an error before anything is deleted, a recording into a
deleted set stops, and a recording into a later set stays in its set.
Undo does not restore a deleted set.
